Doubletake Mirror Updated Ball Mount Kit Doubletake Mirror recently made their excellent mirror kits even better with a complete redesign of their Ball Mount and Arms. By increasing the diameter of the ball mount by .125 inches, they were able to increase the surface tension significantly which keeps the mirror more stable with less clamping force. The larger ball also allows for a through bolt installation. **REPLACEMENT BALL MOUNT KITS ARE SOLD INDIVIDUALLY Features: Includes one 1.125" Ball Stud, 10mm x 1.25 bolt long and short, Reverse Thread Bolt 10mm x 1.25, 10mm x 1.5 short bolt, lock washer.
